Heres my answer for you, but yes you can keep these two together, I've done it no problem, just depends on there temperment. If you get a nice large aquarium with plenty of spots for each fish to have there own territory then you should be all set. Although there is a possibility that one or the other might just snap and kill the other one. It just the luck of the draw basically. Introduce them simultaneously and the same size also. I think that in this hobby that there are no 100% correct answers with fish compatiablity. There are so many exceptions and loop holes that you could almost get any combination under the right conditions to live together. Just my 2 cents take it how ever you want, but best of luck to you and your tank
